IMPROVEMENT l N HARROWS.

Specification forming part of Letters Patent No. 212,043, dated February4, 1879 application filed August 17, 1878.

To all whom it may concern:

Be it known that I, ELI MURRAY, of Bush ville, in the county of Bush andState of Indiana, have invented new and useful Improvements in Harrows,of which the following is a specification In the annexed drawing, makinga part of this specification, I have shown my improved barrow in singleperspective View.

A A are wheels. B is an arched axle similar to that used in straddle-rowcultivators.'

(J is the tongue, and that part of a cultivator may be used for carryingthe harrow attached in the following manner: D is a brace, attached tothe horizontal portion of the axle by yokes and nuts, and sustained bythe chain D, extending to the rear end of the tongue, and D extending tothe hook or bolt D which fastens the double-tree to the tongue. E is thebarrow suspended with its point under the axle. The harrow is drawn bythe chains E. These chains are attached to the draw-bar B by rings, andthe attachment tothe harrow is made adjustable by means of the hasp Ewhich is so constructed as to span the beam of the harrow, andperforated with holes, through which any toothof the harrow may beinserted.

The rods B are attached in a horizontal position to the axle of thecarriage, and their length provides for a play of the draw-chains and alateral movementof the harrow.

The wooden bars or beams of the harrow are attached together in theirfront end by means of plates attached to each and curved upward, uponwhich is bolted a plate, E perfo rated with a hole for the reception ofan iron rod extending from a lever, F. This lever F is for the purposeof suspending the harrow, and has its fulcrum on the middle of thebrace-bar D. A double-hooked catch,-Gr, is

attached to the middle of the transverse bracebar G, which connects thebars of the harrow near its rear end. I

By forcing down the free end of the lever F the front end of the harrowwill be raised, and by engaging the long arm or free end with the catchG the rear end of the harrow will also be suspended, and the harrow bethus held in suspension.

The plate E has also a series of holes in it, through any of which thebolts attaching it to the curved plates may be inserted, by means ofwhich the barrow-beams may be adjusted. What I claim, and desire tosecure by Letters Patent, is- A harrow, in combination with acultivatorframe, A B O, and the chains E and D the adjustable fasteningsE the staple B, the hook D and theperforated adjustable plate E, for thepurposes of attaching and suspending the harrow to the cultivator-frame,substantially as described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

ELI MURRAY. Witnesses:
